I currently use a GRE tunnel to transit traffic from one site to another. However, this tunnel traverses another network which also uses a GRE tunnel to transport their traffic over their resilient path. I do know when using our GRE tunnel over the providers native primary link, there are no problems. When traffic traverses the resilient link (GRE over GRE) large packets do not get through. All routers are setup to use PMTUD and given that the routers are using the built in tunnel interface I believe setting the TCP MSS value is not achievable.
Does anyone know a work around to this problem?
